Owing to the rather large amount of attempted spamming of this forum, I have adopted a policy of regularly deleting any user who has been a member for at least three months but has made zero posts.

I don't imagine that will affect any real users, but if perchance you once signed up a while back but never got round to making a post, you may find that you are no longer a member. The solution is simple: just sign up again. But for your ease and mine, don't sign up till you plan to make a post.
